Hi there, it might help if you would add some basic information, like what Mageia version you installed, and what medium you downloaded (e.g. classic or live installation, 32bit or 64 bit and what desktop environment you chose).
If you did complete the installation, and see the normal Mageia bootsplash animation after a reboot during startup, and if you then only get a black screen, then this means the graphical server did not start properly, which is usually an issue with graphics drivers.
Then message you described about IPV6 or whatever is not related to that at all, it's just the last message during startup before the graphical desktop starts.
For the chipset error in your second post, it would help if you know exactly what it said.
You can find some hints at
https://wiki.mageia.org/en/How_to_chang ... hic_driver and
https://wiki.mageia.org/en/Setup_the_graphical_serverFor now, you can select a safe driver like vesa, which should help you start the graphical server.
And please add some infomation what graphics card you're using, and what computer you're using ( vendor / model ).
